It’s important to have a level of gravel between the drainage pipe and the soil, as this will ensure your pipe doesn’t clog over time. If you have hollow-cored blocks, fill the cores with gravel as well, making sure the top of each course is level so the following course has a proper base to rest upon.

Do you need rebar in a block wall?

Wall Size. … A freestanding garden wall or block privacy fence will require less reinforcing than a basement or other load-bearing wall in a house or other building. An 8-foot-high wall will obviously require more rebar than a 4-foot wall. Very short walls, under 4 feet and laid with mortar, may not require any rebar.

Are poured concrete walls cheaper than block?

Costs vary from region to region, but in this area, poured stem-wall foundations cost about 20% less than block foundations of the same height. In my most recent experience, an 8×16 CMU foundation went for about $6.25 per square foot of wall compared with about $5 per square foot for 10-inch-thick poured walls.

Are poured concrete walls better than block?

How do you calculate concrete blocks?

Measure the length, width, and height of the void in inches, then multiply to get the void’s cubic inches. Multiply the cubic inches by the number of voids in the wall, typically 2 per block. Finally, divide cubic inches by 46,656 to find cubic yards of concrete needed.
